JOHN J. WARREN, OF BROWNVILLE, NEW YORK.

MACHINE FOR WINDING PAPER.

Specification of Letters Patent.

Patented Aug. 29, 1905.

Application filed March 2, 1905. Serial No. 248,099[

To all whom) it may concern.-

Be it known that I, J OHN J. WARREN, a citizen of the United States,residing at Brownville, in the county of Jefferson and State of NewYork, have invented certain new and useful Improvements in Machines forWinding Paper, of which the following is a specification.

This invention relates to improvements in machines for winding paperdesigned for use in connection with paper-making machinery, by which thematerial is made in continuous lengths and wherein the finished paper isreceived by the winding-machine and by it reduced to compactly-woundrolls of different sizes suitable for commercial use; and the inventionrelates particularly to improvements in that class of paper-windingmachines shown and described in Letters Patent heretofore issued tomyself, numbered and dated as follows: No. 631,513, dated August 22,1899.

The invention further relates to paperwinders of the class known asdouble-drum winders, and particularly to machines employing twowinding-drums of unequal size for the purpose of driving or operating adisplaceable receiving-core, which during the" course of the winding ofa roll of paper is constantly kept in operative contact with saidwindingdrums and in which the smaller drum is driven at a higher rate ofspeed rela tively than the larger drum for the purpose of effecting theuniform, compact, and smooth winding of a roll of paper or likematerial.

The object of the present invention is to improve the construction andoperation of double-drum-winding machines of the class referred to, toprovide for greater rapidity, economy, and safety in the operation ofsuch machines, to make certain parts of the device more positive andreliable, and generally to broaden the scope and usefulness ofwindingmachines of the class.

A prominent feature of this invention as compared with previous devicesof the class lies in the substitution of an adjusting-shaft providedwith hand-wheels, clutches, and gears in place of the lever,ratchet-wheels, and links formerly employed to increase or decrease thepressure of the receiving-roll upon or against the winding-drums; andthe invention further consists in substituting sprocket-wheels andsprocket-chains, the latter being provided with adjustable and flexibleparts in place of the plain cables, rollerguides, and weights shown informer inventions.

Another feature of the present invention consists in providing an apronor carrier comprising a band or web of canvas or other suitable materialwhich is disposed on the under side of the large winding-drum. Theobject of this apron or carrier is to receive the free end of the paperas it comes from the slitter and to carry it around the under side ofthe larger drum and thence upward between the two drums, where theoperator catches the paper and makes it fast to the core or shaft uponwhich the paper is to be wound. By reason of this provision the operatoris not required to go under the machine, as has been required to be donein former devices of the class, and the work is therefore more readilyand safely accomplished by the employment of the said apron.

- Other features and parts of the invention will be more readilyunderstood by reference to the drawings/forming apart of thisspecification, and in which- Figure 1 is an end elevation of thewindingmachine embodying my invention. Fig. 2 is a front elevation,partly in section, of the machine with the center portion omitted,showingthe apron or carrier and the various adjustingparts.

Similar numbers of reference are assigned to corresponding partsthroughout the various figures of the drawings.

In the drawings, 1 represents-the frame of i thewinding-machine,preferably made of caststeel.

iron in the form shown herein. 2 represents a shaft driven by anysuitable power and being journaled in the bearings 3, which are attachedto said frame.

4 represents a large winding-drum'which is carried by the shaft 2. Thesmall drum 5 is mounted upon the shaft 6, which is jour-' naled in thebearings7. The shaft 6 is driven by means of a belt connected with theshaft 2.

8 represents a displaceable receiving core or shaft upon which the paperis Wound or rolled. The core 8 is journaled in the vertically-adjustableboxes or bearings 9. These journalboxes are made in two parts, which arejoined together by means of the hinged joint 9. The

upper half of the journal-box 10 is held in a closed position by meansof the spring 11. The hand part 12 is provided for the purpose ofopening and closing the box.

The guide-rods 13 in the present invention are preferably square in formand made of They are pivoted to the base of the frame at 14 by means ofthe pin 14'. The upper ends 13 of these guide-rods are loosely confinedwithin the yoke or slotted aperture 18,v which is formed in the upperends of'the arms 16 and 16. The aperture 18 is made large enough topermit of a slight lateral movement or vibration of the free ends 13 ofv upon which the paper is rolled.

the guide-rods. A cap 19 closes the open end of the yoke or aperture 18and is secured to the point of the arms by means of suitable bolts orscrews. The guide-rods 13 are provided on one of their flat sides with aseries of horizontal grad nations or scales 13 for the purpose ofindicating the diameter or weight of the roll of paper. By the use ofthis scale the operator is able also to readily determine end of theroll of paper could also be raised separately. This feature was employedin the old device at times when the roll of paper for any reason builtup or increased more rapidly at one, end than the other, and bymanipulating the hand-levers referred to the roll could be keptsubstantially level throughhave shown an adjusting-shaft 20, which ismounted in the journaled bearings 21, supported by the upright arms 16and 16 of the frame, preferably in the position and in relation to theother parts of the machine, as shown in Figs. 1, 2. and 3. Theadjustingshaft 20 is not driven by power; but it is intended to berotated wholly or partially by means of the hand-wh eels 23 and 25 andalso'by its indirect connection with the sprocketchains located ateither end of the machine, which connect with and are operated by thepaper-roll during the winding of the same. The adjusting-shaft 20, asshown in detail, Fig. 5, is equipped with a number of cooperative partswhich adapt the same to be operated to effect a number of differentadjustments producing various results. Theseadjustments are accomplishedin the first place by means of the hand-wheels 23 and 25, which have theeffect of levers or cranks, mountedv on the end of the shaft, whichprojects out beyond the upwardly-extending. bracket-arms 16 of theframe. These hand-wheels are both disposed concentrically with shaft 20and are capable of being rotated by hand either separately or togetherby means of afeather 26 and a clutch 27, the latter being interposedbetween said hand-wheels. The interlocking of the two hand-wheels by theaid of said clutch is maintained by means of the tension of spring 33.(Shown in Fig. 2.) The handwheel' 23 is secured to the hollow shaft orsleeve 22,,also' mounted on the shaft 20 by means of a feather 24,(shown in Fig. 5,) while the hand-wheel 25 is slidable on the spline orfeather 26, (shown in the same fig ure,) and when in engagement withsaid spline is rotated with shaft 20. By this arrangement the wheel 25may be pulled outwardly against the spring 33 until the clutch 27 is 7released, as shown in Fig. 3, and then turned to the right or left toeffect the desired adjustment. It will be noticed that the feather 26does not extend beyond the hand-wheel when the latter is in engagementwith the clutch 27 and wheel 23, and when hand-wheel 25 is pulledoutwardly against spring 33 the full distance allowed it becomes freefromthe.

and 29 are preferably in the form of disks, and the disk 28 is providedon its face side with a series of sockets or holes 30, arranged in acircle in close order, as shown in Fig. 6. The disk 29 is provided witha series, preferably four, of dowel-pins or projecting points 31, (shownin Fig. 7,) which are arranged so as to engage corresponding holes 30 ofdisk 28, and by that means the handwheels 23 and 25 are interlocked andmade to operate as one wheel or part. In Fig. 3 handwheel 25 is shown tobe out of engagement with the clutch 27 and hand-wheel 23. The functionsor objects of these adjustable means are as follows: In winding a freshstrip of paper upon the core or roll 8 as it comes directly from thecalenders the web of the material throughout is not always of the sameconsistency and thickness, and therefore it is impossible to effect theeven or smooth winding of the same upon the receiving-cores unless somecompensating means are provided therefor. Sometimes one side is thickeror harder than the other, and at another time the same side or perhapsthe center portion is harder or softer than the edges, and the rolls areoften formed with sufiicient unevenness or irregularity as todistorttheir appearance and destroy their value for commercial use. For.this reason if one end of the roll of paper builds up or increases morerapidly than the other the operator will take hold of the handwheel 25and pull it lengthwise of the shaft 20, so as to free it from engagementwith the clutch 27. Then he will turn it either to the left or right, asthe case may be, and reset the clutch in a position to effect theraising of the end of the paper-roll which requires leveling up. If thefarther end of the roll requires leveling, then he will turn thehand-Wheel 25 to the right the required distance and set the clutch in anew position. This operation raises the farther end of the roll ofpaper, but does not affect the near end of said roll. In this connectionit might be well to explain that when the hand-wheel 25 is freed fromthe clutch, but still in engagement with the feather 26, if the saidwheel is turned in either direction while held in said position it Willeffect the turning of the shaft 20, the pinion 43, and also spur-gear4:0 and not operate the sleeve 22, the pinion 37, or the spurgear 40;but as soon as the hand-wheel 25 is allowed to connect with Wheel 23 bymeans of the clutch then the said shaft 20 and all of the connectedparts, including both hand-Wheels, will operate together, and both endsof the paper-roll will be affected in the same way. By the raising ofthe farther end of the paper-roll as just described a certain amount ofthe weight of the roll will be relieved from the Windingdrum, and-thepaper, therefore, will not be wound as tightly on that end of the rollas on the other end, where the weight has not been so relieved. In thismanner the leveling up of the roll is accomplished, and when done thehand-wheel 25 is left in the position last named until the roll iscomplete. If the forward end of the roll becomes out of level, theoperator pulls hand-wheel 25 out of engagement with clutch 37 and holdsit While an-' other Workman turns hand-wheel 23 to the right a notch ormore, and by that means the shaft 20 remains stationary, While thesleeve 22 and the pinion 37, keyed thereon, will be rotated thereby, andsaid gear being in mesh with spur-gear 40 will operate the latter, andthrough the sprocket-and-chain connections the weight of the roll ofpaper at the forward end will be relieved from the drums in the mannerdescribed. By the use of clutch 27,

hand-wheels 23 and 25, and shaft 20, together With the gears, sprockets,and chains, the entire weight of the roll of paper may be lifted off thewindingdrums, or any portion of said weight may be relieved during thewinding of the paper on the roll, as described. The adjusting-shaft 20Will make from one to ten rei'olutions in Winding the different-sized rols.

A zero or level mark 44 is placed on the outer edge of each of theclutch-disks 28 29, as shown in Fig. 2. These are for the purpose ofproviding a gage by means of which the adjusting parts are set to bringthe core or shaft upon which paper is to be wound in a true and levelposition. Before the paper is Wound on the core the hand-wheels are setwith the zero-mark 44 on each corresponding. Then the receiving-core 8is level. After a roll has been completed and removed a new core orshaft is placed in the journalboXes 9 and the hand-Wheels and shaft 20turned backward till the core is lowered to the starting-point betweenthe Winding drums. Then the operator sets the handwheels at zero, asdescribed, and the core is started in a true and level manner.

The spring 33 is held in place on shaft 20 by means of the collar 34,secured to said shaft by the pin or set-screw 35.

The pinion 37 and the ratchet-gear 38 are cast in one piece and aresecured to the sleeve 22 by means of the key or feather 39. Being thusmade rigid on said sleeve, these parts all rotate together.

4:0 and 40 represent the large spurgears Which-are loosely mounted uponthe stationary rod or shaft 41, secured to the upper ends of the arms 16and 16. The rod 41 in addition to carrying the large spur-gears alsoserves as a tie or brace to the upper parts of the frame. The gears 40and 40 are held in position opposite to and in mesh with the pinions 37and 4:3 by means of the collars 42, which are made fast to the said rodby means of suitable set-screws. The sprocket-Wheels 4:5 and 45 are caston the hubs of the spurgears 40 and 40, respectively. The said gears,

Ioo

together with the sprocket-Wheels, are revo- 46 represents a sectionalview of the cen- V tral portions of the gears 40 and 4:0 and also of thesprockets 45 and 45'.

The sprocket-chains 4:7 and 47 are each provided with the .rod or linkportion 49, which is threaded throughout its length, except its upperend, which is formed into a hook 50, by means of which the said rod orlink is connected with one end of the sprocket-chain.

The lower end of the rod 49 is fitted with the nut 51, which is attachedto said rod by means of threads. A loop 52 is formed upon the nut 51 andis adapted to connect with a link of the sprocket-chain. The threadedrod or link 49 is provided with the jam-nuts 54:, disposed immediatelyabove the spring 55, and in addition to'holding the spring in place alsoserves as means for increasing or diminishing the tensionof said spring.The lower end of spring 55 bears against the laterally-extended arm orlug 58 of the journal-box 9,

. of adjusting the core or shaft 8 horizontally,

the full purpose of these parts just referred to being to afford a meansof relieving or increasing the weight of the roll of paper upon thewinding-drums when operated in connection with the adjustable meansdescribed and by the employment of the spring 55 to provide for slightvibration of the roll during the winding of the same.

The square guide-rods 1 3, which support the journal-boxes 9, passthrough a square apertu-re '61, formed in the body of said boxes, asshown in Fig. 8. By this means provision is made for the sliding of saidboxes upwardly and downwardly on said guide-rods. The rods13 have aslight lateral movement or play by reason of the yoke or slotted opening18 and the pivot 14. The axis of 'thepaper-roll as it increases indiameter by reason of the sliding of the journal --boxes on theguide-rod 13 moves upwardly in a substantially vertical course, and thelateral play of the guide-rods merely provides for any vibra tion oroscillation of the roll of paper incident to the slight unevenness ofthe roll and the high rate of speed at which said roll is driven duringthe course of the winding.

The sprocket-wheels 62 are pivoted to the inner side of the frame ateach end of the machine. These are employed for the purpose ofsupporting the sprocket-chains and preventing them from interfering withthe other working parts of the machine.

The sprocket-chains at each end of the machine are provided with theturnbuckles 63, which are employed for the purpose of adjusting thelength of said chainsthat is, to increase or decrease the slack ortension of said chains. The turnbuckle 63 is comprised of the bodyportions 64 and 65. These. two parts are connected by means of the screw66, which is cast integrally with the body portion 65, the free endthereof being threaded to correspond with and engage theinternallypasses through the hole 71 in the upper endof the body partand extends downwardly through the coiled spring 72 and the nut 73. Thelower end of the bolt 69 is upset to form %a head on the under side ofthe nut 73. object of the said turnbuckle provided with a spring andbolt in the manner described and The shown 'is to permit of the bodyportion '65 being turned either to the right or to the left upon saidbolt 69, as on a swivel, for the purpose of shortening or lengtheningthe sprocket-chain, and at the same time, by reason of the employment ofthe spring 72 in connection with the bolt 69 and the nut 73, a

certain amount of resilience or yielding tension is provided. This hasbeen found to be necessary in order to prevent the cramping or breakingof the sprocket-chain in cases where too great a tension or strain hasbeen occasioned by the operation of the turnbuckle or from other causes,

The ratchet-wheel 38, cast with the spurgear 37 and mounted upon thesleeve 22, is provided with the pawl 75, having the handle or lever 76pivotally attached to the upright arm 16 by means of the bracket 77 andthe ,pin 78. The said pawl is located so that it may. engage theratchet-gear 38 and maybe thrown into or out of such engagement by theoperator by *means of the handle 76. The object of this ratchet-gear andpawl is to enable the operator to sustain or hold the weight of an extraheavy roll of paper-in other words, to prevent the recoil of the shaft20 during the opration of the hand-wheels and related parts whenadjusting or raising aheav-y roll of paper.

The shaft 20 is also provided at one end with a'sma'll drum or sheave80, as shown in Figs. 2, 3, 5, and 9, to which is attached the cable 81and the weight 82. "The said cable is adapted to be coiled or woundaround said drum in either direction, as shown by the full and dottedlines in Fig. 9. The object of the drum, cable, and weight referred tois to provide a suitable tension-and driving power for the shaft 20 andalso for the large spur-gears and sprocket-wheels mounted on thestationary shaft or rod 41, the weight referred to being heavy enough torotate the said drum and shaft 20, as well as the other connected parts.The weight 82 is also employed as a counterweight to retard the rotationof shaft 20, and therefore allow the paper-roll to bear less heavilyupon the winding-drums." In case it is desired to rotate the shaft 20toward the right the cable 81 is placed on the drum or sheave in themanner shown by the full lines in Fig. 9, and-when desired to rotatesaid shaft in the reverse direction said cable and weight are disposedas shown by the dotted lines in the same figure.

The web or canvas comprising the apron or carrier 85 is preferably aboutone foot in width and is endless in form, resembling a broad belt. Thisapron is mounted upon and carried by a series of rollers or drums, oneof which, 86, acts as a driver for said apron. The other three rollersor drums 87 are merely idle carriers, disposed, preferably, as shown inFig. 4c of the drawings, for the purpose of carrying and guiding theapron so as not to interfere with other parts of the machine. Thepreferred position of the apron or carrier with reference to the largedrum 4 is substantially opposite the center or middle of said drum, asshown in Fig. 2 of the drawings. This has been found to be the mostconvenient and serviceable location for said apron, although it may atany time, if desired, be shifted toward either end of said drum andperform the same work. q '88 represents the four guide rods or bars uponwhich the apron rollers or drums 87 are adjustably and operativelymounted. These rods or bars are secured to the base of the frame ateither end of the machine, as shown by the numeral 90. Before startingto wind the paper the broad end of the strip of paper is folded or cutin the form of a V, as shown by the dotted lines 91 in Fig. 2, the pointof which corresponds with the center of the apron. To begin the winding,the point 91 of the paper is inserted or fed between the apron and thedrum 4 at 87 at the front of the machine, and it is then carried aroundto the receiving-core in asmooth and even manner. The apron or carrier85 during the whole course of the winding is held in contact with thelarge drum 4, as shown in Fig. 4:, under sufijcient tension to keep boththe said apron and the web of paper even or flat against the surface ofthe said drum, thereby preventing the central portion of the strip ofpaper from becoming wrinkled or otherwise distorted. The apron drum orroller 86 is held constantly againstthe winding-drum 4 under a tensionstrong enough to insure its being driven, and thereby cause said apronto travel at the same relative speed as the drum and the paper. Inpractical operation the two winding-drums are driven in the samedirection, (as indicated by the arrows in Fig. 1,) and the smaller drumbeing of less circumferential measurement must travel at aproportionately higher rate of speed. This is accomplished by theunequal pulleys 92 93 and the belt 94:. (Shown in Fig. 9.) By reason ofthe fact that the drums are of unequal size, as herein explained, theroll of paper, because of the position of its hearings on the pivotedguide-rod 18, will bear heaviest against the larger drum, as shown inFig. 1, from which it will be seen that the angle of bearing withrelation to the paper-roll and the large and small drums differsrelativel y to the respective diameters of the drums and also to therelative position of the large and small drums.

The axisof the small drum, as shown by the drawings, is placed on ahigher plane horizontally than the axis of the larger drum. The positionof the two drums for producing the best results is preferred to besubstantially as shown by the drawings.

96 represents a series of spirally-shaped grooves .or recesses which areformed or out in the surface or circumference of each of the drums 5 and6, as shown in Fig. 2. These grooves or recesses are provided for thepurpose of compensating for the rough or uneven calendering of the sheetor strip of paper. It frequently occurs that sections here and there inthelength and width of the continuous strip or web of paper are ofdifferent degrees of hardness. Sometimes one edge of the strip isthicker or softer than the other, and at other times the central portionfor a distance is slightly different from either of the edges. For thatreason I have provided the grooves on the surfaces of the drums, and inthat way as the paper passes under tension between the drums and thereceiving-roll such discrepancies are in a great measure compensated forby the paper being pressed or crowded into the recesses or grooves,which take care of much of the extra fullness or unevenness in the web,and the winding continues on the roll in a comparatively smooth and evenmanner. The grooves are formed spirally to prevent the paper from beingfluted or crimped, as would be the case if the grooves were formedstraight or horizontally with the drums. The grooves or recesses arepreferably placed close together, about a quarter of an inch in width byone-eighth inch in depth, to produce the best results. They are arrangedon each of the drums in the same manner, and both drums travel in thesame direction when in operation.

97 represents the continuous length or strip of paper as it comes fromthe calenders and is received by the winder and wound upon the roll'98,as shown in Fig. l.

The hand-wheel 23 is provided with a groove 99 on its outer edge orperiphery, which is adapted to receive a cable 100, to which isconnected a weight or a series of detachable weights 101. This provisionis made for the same purpose as the drum and cable 81 on the oppositeend of shaft 20. The object in having the cable and weight at each endof said shaft is for the purpose of greater convenience in carrying outthe operations of the winding-machine and also to provide additionalweight, which is sometimes required in order to effect aproper'adjustment of the winding parts. The cables are attached to thedrum 80 and the hand-wheel 23 in such manner that either or both of themmay be quickly removed (see 80) if for any reason no weights arerequired. The Weights referred to are for the purpose also'of increasingor decreasing the pressure of the roll of paper on the Winding-drums.The weights may be used separately to affect the endof the roll at whichthey are attached and not the other end, or they may be employed tocontrol or affect the entire shaft 20 and all the related parts.

The semicircular-shaped guard 103, having its bearings 104 on shaft 6,is provided with the projecting arms 105 andis connected with therearwardly-extending lug 106 of thejournal-box 9 by means of the link orrod 107 and the pins108. This guard by reason of its connection with themovable journal-box 9 and its loose bearing upon the shaft 6 is operatedautomatically. When the receiving-core 8 is mounted in the movable boxes9 and placed in between thev winding-drums, the guard 103, by means ofthe said arm and link, is swung forward to within an inch or two of thesaid core, and then as the roll of paper increases the guard is turnedbackward, but

always maintaining the same relative space or distance from the roll.The dotted lines at 109 represent the position of the core 8 withreference to the two drums at the start of the winding. 1 r

The stands or brackets 110, located at the rear of the machine at eitherend, are provided for the purpose of receiving or supporting the shaftor core 8 either before or after the paper is wound upon the same. Thesestands or brackets are secured to the frame in a suitable manner and forconvenience are disposed as shown in Figs. 1 and 4.

111 represents a spreader for the paper, such as is commonly used inconnection with paper-winding machines.

During the course of my experimenting and from actual practice withdouble drumwinding machines I have found that much better results areattained by the employment of drums of unequaldiameter and have foundthat the difference in size of the drums should be relatively about twoto one. Where drums of the same size are employed, a roll of papercannot be wound with the desired evenness and much difliculty inoperating and great waste of time and material have resulted from theiremployment. The reason for this I have found to lie chiefly in the factthat the weight of the paper-roll will bear substantially evenly uponeach of the two drums,

and for that reason in machines where drums of'equal size are employedthe drums must be mounted and maintained so that their horizontal axeswill be substantially on a level. It has also been found that one,preferably the first drum in the orderof the winding, must be at leasttwo feet in diameter in order to produce the best results, and if thedrums are of the same size the bearing-points of the roll of paper onthe two drums after the roll has increased considerably in size becomeswider apart, and this has the effect of destroying the effectiveness ofthe winder. Under such a construction the same amount of weight of thepaper-roll will be borne by each drum, and hence it has been foundimpracticable to increase the speed of the second drum to the extentnecessary to produce compact and even winding without tearing ordistorting the paper. On the other hand, by the use of the drums ofunequal size, constructed as shown and described herein, the smallerdrum is preferably placed at the rear of the machine and is broughtnearer to the larger drum,thereby lessening the distance between thedrums and the roll of paper, which is of great advantage in drum-windingmachines, and the bearing-surface between the small drum and the roll isrelatively only half as great as that between the large drum and theroll of paper. Hence as the weight carried by the smaller drum is somuch less than that borne by the larger drum it has been found possibleto provide for a slight increase in the speed of the small drum. This isaccomplished by decreasing the diameter of pulley 93, mounted on shaft 6'of the smaller drum, five to ten per cent. smaller than theproportional diameter of the two drums when driven at equal surfacespeed. This increase of speed is fixed at such a small degree that whileit exerts a slight pull on the web of the paper, just. enough to keep itstretched tight on the portion of the roll already wound, there is notenough strain to cause the tearing or distorting of the material. 1f thewinding-drums travel at the same rate of speed relatively and being keptconstantly in contact with the roll of paper, which is increasing indiameter with each revolution, the layers or coils of paper afterpassing from the large or driven drum onto the roll apparently loosen orslacken, and it therefore became necessary to devise some means tocorrect or regulate this slight defect in the winding, which if allowedto continue for a number of revolutions would result in wrinkling ordistorting the paper on the roll. Hence by reducing the size of thebelt-pulley on the shaft which carries the small drum to the extentdescribed it will increase the speed of said drum sufliciently to exerta slight pull on the paper, causing the tightening of the layers ofpaper, and thereby effect the cornpact and even winding of the roll. Byreason of the faster travel of the small drum there is a slight constantslip of the said drum at the point where it makes the frictional contactwith the paper-roll. By the use of the small drum, disposed asdescribed, the workmen are able to get nearer to the roll of paperduring the progress of the winding and are thus enabled to make splicesor to do any other necessary work more conveniently. One of the chiefadvantages derived from the use of drums of unequal size arises from thefact that alarger surface or bearing contact is provided, and thereforea greater purchase is given to the roll of paper, which has been foundto be necessary to properly carry out the purposes of the machine. Italso allows the spool or core when first starting to wind to drop downbetween the rolls or drums a greater distance and still be within easyreach of the operator. Under this form of construction the angle ofbearingor contact is such that it affords a better grip on the core orshaft upon which the paper is wound. By reason of'the difference of theangle of bearing or contact referred to a larger proportion of theweightof the paperroll is brought to bear upon the larger orpower-driven drum, while the smaller drum only carries such proportionof the weight as is necessary to prevent or avoid deflection of theshaft or core on which the paper is being wound.

It is not claimed that the double-drum feature of the present inventionis entirely new to the art, as machines having a plurality ofwinding-drums have been in use heretofore; but it is claimed that doublewinding drums or rolls of unequal diameter arranged and operated in themanner herein shown and described are essentially new and constitute animprovement over existing forms or makes of paper-winding devices.

Believing that the operation of my device will be fully understood inthe foregoing, further special explanation thereof is unnecessary.

It is obvious that many of the details of the construction of the devicemay be varied without departing from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
